This invention relates'to a foldable and collapsible bed, such as'usedby campers,

tourists, and the like, and particularly, to a mattress for said bedwhich is secured to a tensioned flexible sheet, such as a. sheet ofcanvas. In beds of the prior art where a tensioned sheet or mattress isused the tension has often been applied to the mattress. This destroysand tears the mattress and renders the same objectionable for sleepingpurposes. If the supporting. or tensioning means are not secured to themattress the mattress is apt to contract and become crumpled and lumpy.I

It is an object of this invention, therefore, to provide a collapsiblebed structure including a tension flexible sheet having a thin mattresssecured thereto which is adapted to be rolled or folded with said sheet,the mattress being slightly longer than the sheet so that suflicientslack is provided thatwhen the sheet is tensioned the mattress'will notbe under tension.

It is a further object of the invention to provide a collapsible'bedstructure comprising a flexible sheet having tensioning means securedadjacent each of its ends, which means are supported by said bed,together with a mattress secured at its ends to the ends of said sheet,the end portions of the sheet and mattress overlapping the tensioningmeans.

It is more specifically an object of the invention to provide such astructure as set forth in the preceding paragraph in which said flexiblesheet is provided with spaced longitudinallyv extending reinforcingportions, and in which the tensioning means is secured to rods disposed,respectively, at each end of said sheet and loosely secured thereto,said rods preferably being secured in a loop formed by folding themattress.

These and other objects and advantagesof the invention will be fully setforth in the following description made in connection with theaccompanying drawings in which like reference characters refer to thesame parts throughout the different views, and in which Fig.1 is a viewin side elevation of the device, a small portion being shown in verti--cal section;

Fig. 2 is a top plan view of the device with certain portions brokenaway to show the underlying parts;

Referring to the drawings, a bed is shown comprising'a frame havingconnectible end portions, each of which comprises an end bar 7 which maybe formed of pipe or tubing and which, has at each end thereof, abifurcated member 7*. Side bars 8 are pivoted to the portion 7 onvertical pivots and leg members 9 having the forked or bifurcatedmembers 9 at their upper ends are pivoted to the members 8 adjacent themember 7 about horizontal pivots. The members 8, at one end of theframe, are formed with pointed ends 8*, While the ends of the members 8,at the other end of the frame, are formed with concave portions 8 inwhich the ends 8 are adapted to fit and form a substantially universaljoint. A sleeve 10 is slidable on the bars 8 so that it may be disposedover the adjacent end portion of the members 8, as shown in Figs. 1, 2and 6.

A flexible sheet 11 of fabric material, suchas strong canvas, isprovided and this sheet, preferably is provided with spacedlongitudinally extending reforcing portions. While these portions may bevariously formed, in the embodiment of the invention illustrated, theyare shown as formed by folding the canvas to form a double or reversefold or plait 11 held in such shape by spaced longitudinal rows ofstitching l1". A rod 12 is loosely secured to the sheet 11 adjacent eachof its ends so as to extend transversely thereof, and while this rod maybe variously secured, in the embodiment of the invention illustrated, itis shown as disposed in a loop fold 11 formed by folding the sheet 11transversely in a reverse fold and securing said fold by a transverseline of stitching 11. At one end of the sheet 11 a series of tensilesprings 13 are provided having one of their ends formed as hooks andextending around the rod '12 through the loop 11. It will be noted thatcertain of these springs are alined with theportions 11". The springsare secured at their outer ends by headed and nutted screws 14 to'splitrings 15 which embrace the rod 7. At the other end of the bed .the rod12 is embraced by a series of chain links 16 forming the inner end linksof chains 16, the outer end links of which are secured to split rings 15which are similar in construction to the rings 15 already described andsecured to the said end links in the same manner as the ends of thespring 13 are secured. The end portions of the sheet 11 extend over thesprings 13 and rods 7 at one end of the bed and over the chains 16 androd 7, respectively, at the other end of the bed. A comparatively thinmattress 17 is provided which, preferably will be provided with theusual tufts 17, which mattress is adaptd to be folded or rolled up. Themattress 17 is slightly longer than the sheet 11 and is secured at itsends to the end of said sheet in any suitable manner, as by the line ofstitching 18.

In operation, when the bed is to be erected, the ends of the members 8will be engaged, the sleeve 10 atthis time being entirely on the members8 at one end of the bed. The ends of the members 8 bein engaged and thelegs disposed downward y, as shown in Fig. 1, the members 8 can bepressed down into horizontal position and the sleeve 10 slid thereover,so that the canvas 11 will be tensioned. The tensioning stress istransmitted to the rods 12 and by the rods to the sheet 11. As stated,the mattress 17 is somewhat longer than the sheet 11 and slack isprovided so that when the sheet 11 is under tension the mattress willnot be under tension but will simply lie in proper and loose conditionon the sheet, the ends of said sheet and mattress overlapping thesprings 13 and the chains 16, as well as the bars 7, as alreadydescribed. The bed is now in condition for use and a pillow or othersimilar means can be placed under one end of the sheet 11 and mattress17.

When the bed is to be colla sed, the sleeves 10 are slid onto the memera 8 at one end of the frame so that the bars 8, at each end, can beswung at an angle and disconnected. Each bar 8 will then fold along oneof the end bars 7, the le 9 also folding along the bars 8. When t eparts are so folded the same can be rolled up with the sheet ll'andmattress 17 so that the whole structure can be collapsed into a verysmall volume. If the sheet 11 or spring 13 should become somewhatextended sothat sufiicient tension is notprovided, a link can be takenup in the chain 16 so that pro er tension can then be secured. The reinorced portions' 11 of sheet- 11 insure that the said sheet can be highlytensioned without any damage or danger of tearing and "these reinforcinportions form spaced supporting zones. 7 he mattress 17 not being placeunder tension and yet being held properly in place, is not damaged orunduly stretched so as to get out of shape and thus remains in properand comfortable condition for a long period. From the above descriptionit is seen that a plicant has provided a very simple and e cient, aswell as durable folding bed andmattress structure therefor. The devicehas been amply demonstrated in actual practice and found to be verysuccessful and is meetin with great commercial favor.

It will of course, be understood, that various changes may be made inthe form, details, arrangement and proportions of the parts withoutdeparting from the scope of applicants invention, which generallystated, consists in a device capable of .carryin out the objects aboveset forth, in the nove parts and combinations of parts disclosed anddefined in the appended claims.

What is claimed is 1. A- folding bed'structure having in com.- bination,a flexible sheet of fabric material, a support-spaced from each endthereof, a series of spaced means secured adjacent each end of saidsheet and secured at their opposite ends, respectively, to saidsupports, one of said series of means being resilient, and acomparatively thin foldable mattress permanently secured at its ends tothe ends of said sheet with suficient slack so that when said sheet istensioned, said mattress will not be under tension.

2. A collapsible bed structure having in combination, a flexible sheetof fabric material having spaced longitudinally extending reinforcedportions, a series of spaced tensioning means secured adjacent the endsof said sheet and alined with said portions, one of said series beingresilient, and a mat tress permanently secured to the ends of saidsheet, said mattress being slightly longer than said sheet whereby saidmattress is not tensioned when said sheet is ten- .sioned.

V 3. A collapsible bed structure having in combination, a flexible sheetof fabric material, a rod extending transversely of said sheet adjacenteach end thereof and loosely secured thereto, the end portions of saidsheet extending beyond said rod, a mattress of slightly greater lengththan said sheet having its ends permanently secured to the ends of saidsheet, and tensioning and su portmg means secured to said rods anddisposed beneath the end portions of said sheet and mattress.

4. A collapsible bed structure having in combination, a flexible sheetof fabric material, said sheet being reversely folded and transverselystitched adjacent each end to form a transversely extending 100p, rodsdisposed respectively in said loops, spaced tensioning and supportingmeans embracing each rod and extending therefrom, the ends of said sheetoverlying said tensioning means, and a comparatively thin mattress tressso that when said sheetis tensioned W said mattress will not betensioned.
